7+ (-5) = 2.
Therefor, 4^2 would be the right answer.
They are similar. Set the proportions equal to each other
(x + 8)/8 = (x+14)/12
Cross multiply
(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)
12(x + 8) = 8(x + 14)
Distribute the 12 and 8 to the corresponding monomials inside the parenthesis
12(x + 8) = 12x + 96
8(x + 14) = 8x + 112
12x + 96 = 8x + 112
Isolate the x. Subtract 8x from both sides and 96 from both sides
12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)
12x - 8x = 112 - 96
4x = 16
Isolate the equal sign. Divide 4 from both sides
4x/4 = 16/4
x = 16/4
x = 4

Answer:
Option 2
Step-by-step explanation:
Option 1: $68.85
Option 2: $68.80
Option 3: $70.9
Option 4: $71.81
U=units
A=πr²
=π(44)²
=6082.12u²
6082.12/121= 50.27
A=πr²
50.27=πr²
r²=50.27/π
r=√16
r=4u
